Surface more info on preprocessing tools

[emmahodcroft]

From feedback from Aine, she would like more info on the preprocessing of sequences.

For example, how the alignment constructed, what's reference used, whether masked, etc.

If we are tracking the version of Nextclade and the version of Nextclade dataset that's being used in the metadata (or the equivalent generic terms for any other tool in the preprocessing pipeline), this would be an easy thing to surface on the sequence detail page and in the metadata download file.

We may need to discuss exactly what we'd like to store and surface. If these could be (optionally) links, it could save effort in trying to explain by linking directly to the tool where users can figure this out for themselves/use that tool's docs (in our case that would be Nextclade for Pathoplexus but could of course be any tool that someone may want to link to).

We link to the reference in the info button on the sequence details page. It would be great to also add the nextclade version we use there as well - or at least a link to an info page about our preprocessing pipeline version if we would like this to be more customizable.
